AbstractAnomalous aortic origin of the coronary arteries is associated with exercise-induced ischaemia, leading some physicians to restrict exercise in patients with this condition. We sought to determine whether exercise restriction was associated with increasing body mass index over time. From 1998 to 2015, 440 patients ⩽30 years old were enrolled into an inception cohort. Exercise-restriction status was documented in 143 patients. Using linear mixed model repeated-measures regression, factors associated with increasing body mass index z-score over time, including exercise restriction and surgical intervention as time-varying covariates, were investigated. The 143 patients attended 558 clinic visits for which exercise-restriction status was recorded. The mean number of clinic visits per patient was 4, and the median duration of follow-up was 1.7 years (interquartile range (IQR) 0.5–4.4). The median age at first clinic visit was 10.3 years (IQR 7.1–13.9), and 71% (101/143) were males. All patients were alive at their most recent follow-up. At the first clinic visit, 54% (78/143) were exercise restricted, and restriction status changed in 34% (48/143) during follow-up. The median baseline body mass index z-score was 0.2 (IQR 0.3–0.9). In repeated-measures analysis, neither time-related exercise restriction nor its interaction with time was associated with increasing body mass index z-score. Surgical intervention and its interaction with time were associated with decreasing body mass index z-score. Although exercise restriction was not associated with increasing body mass index over time, surgical intervention was associated with decreasing body mass index z-score over time in patients with anomalous aortic origin of the coronary arteries.

Kronika Ilustrowana, manuskrypt z 1360 r., znana pod łacińską nazwą Chronicon Pictum, kończy się opowieścią o bitwie pod Posadą. Starcie zbrojne, do którego doszło w 1330 r. między Węgrami a Wołoszczyzną, dziś jest pamiętane jako doniosłe zwycięstwo nowo powstałej dynastii Basarabów. Dwie miniatury obrazujące bitwę pod Posadą zawarte na kartach 143 i 146 Kroniki Ilustrowanej, często pomijane w kontekście opracowania historycznego, stanowią integralną część opowieści i uzupełnienie tekstu pisanego. Obraz pełni funkcję zapisu wydarzeń oraz dodatkowo dostarcza informacji na temat ówczesnych strojów, uzbrojenia i artystycznych środków wyrazu. Analiza bitwy pod Posadą na podstawie XIV-wiecznej Kroniki Ilustrowanej stanowi próbę uzupełnienia badań historycznych o analizę malarstwa miniatorskiego.

Full textAbstract:
Abstract Gamma-hydroxybutyric acid (GHB), usually reported as rape drug in drug-facilitated sexual assaults (DFSA), is an endogenous substance in human body and is also found in many beverages. This may lead to data misinterpretation in forensic cases. Herein, we aimed to collect evidence about natural GHB presence in 13 energy drinks (ED). After a liquid–liquid extraction with acidic ethyl acetate, samples were derivatized with BSTFA 1% TMCS. Analyses were carried out by a GC–MS system in SIM mode (GHB, 233, 234, 143 and 147 m/z; GHB-d6, 239, 240, 120 and 206 m/z). GHB was present in all the samples at very low concentrations ranging from 98 to 197 ng/mL. Thus, GHB presence in ED is not exclusively related to exogenous addition. Since the GHB levels are far lower than the minimum active dose (i.e., 0.5 g), it is not expected to induce any effect.

Crystals of N-(trifluoromethyl)formamide, C2H2F3NO, (I), N-(2,2,2-trifluoroethyl)formamide, C3H4F3NO, (II), and 2,2,2-trifluoroethyl isocyanide, C3H2F3N, (III), were grown in situ on an X-ray diffractometer and analysed by single-crystal X-ray diffraction methods at low temperatures. Crystal data: (I) orthorhombic, P212121, a = 4.547 (2) Å, b = 5.947 (3) Å, c = 14.731 (9) Å, V = 398.3 (4) Å3, Z = 4, M r = 113.05, T = 143 K, D x = 1.885 Mg m−3; (II) monoclinic, P21/n, a = 4.807 (1) Å, b = 16.707 (3) Å, c = 6.708 (1) Å, β = 109.90 (1)°, V = 506.6 (2) Å3, Z = 4, M r = 127.07, T = 141 K, D x = 1.666 Mg m−3; (III) orthorhombic, P212121, a = 5.668 (2) Å, b = 9.266 (3) Å, c = 8.626 (2) Å, V = 453.0 (2) Å3, Z = 4, M r = 109.06, T = 163 K, D x = 1.599 Mg m−3. The results showed that in the crystal both formamides (I) and (II) are exclusively present in the form of the Z isomer, although measurements of solutions of (I) have shown that the E isomer prevails [Lentz et al. (1987). Angew. Chem. 99, 951–953]. In addition ab initio calculations for (I) predicted the E isomer to be the more stable one. In compound (III) the isocyanide group is staggered with respect to the trifluoroethyl group. In the crystal packing of (I) and (II) intermolecular N—H\cdotsO hydrogen bonds generate infinite chains. In (I), these chains are linked to form sheets by C—H\cdotsO contacts. In the crystal structure of (III) each isocyanide dipole is surrounded by four electronegative F atoms with intermolecular C\cdotsF contacts between 3.4 and 3.5 Å.

Ps 6 jest pierwszym z siedmiu psalmów pokutnych (Ps 6; 32; 38; 51; 102; 130; 143). Ww. 2-3 ukazują wszechobecną moc grzechu. Grzech ma wpływ na całą egzystencję, o czym świadczy użycie słów „kości” (fizyczne) i „dusza” (cała istota). W istocie psalmista próbuje błagać Boga, mówiąc: „Jeśli mnie nie wybawisz, będziesz miał o jednego czciciela mniej”. Psalmista kładzie wysoką wartość na chwałę Boga jako kartę przetargową.

Background/Aim. Measurement of intraocular pressure (IOP) over therapeutic silicone hydrogel soft contact lenses by a non-contact method of tonometry could be applied in opthalmologic practice but the results obtained are still controversial. The aim of this study was to evaluate the effect of spherically designed silicone hydrogel soft contact lenses and their power on values of IOP measured by using a noncontact tonometry method. Methods. We measured IOP with and without spherical silicone hydrogel soft contact lenses on 143 eyes of 80 subjects who did not have any ocular or systemic diseases. Results. The Wilcoxon statistical analysis test for ranking average values of IOP measured on 143 eyes over a spherical silicone hydrogel soft contact lenses showed significantly higher values compared to those measured with no contact lenses (15.81 ? 3.46 mm Hg vs 14.54 ? 3.19 mm Hg; respectively; Z = -5.224, p = 0.001). Refractive power analysis of the contact lenses of -9.00D to +6.00 D showed a significant difference of IOP in the range from 0.00D to -6.00D. Conclusion. Non-contact tonometry is not an accurate method of IOP measuring over spherical silicone hydrogel soft contact lenses which belong to therapeutic contact lenses.

Health care professionals (HCPs) and trainees feel ill-equipped to discuss weight-related issues with children and their families. A whiteboard video for HCPs and trainees outlining strategies to communicate about weight was developed and evaluated. Seventy HCPs, including 15 trainees, participated in the baseline assessment and 39 repeated measures 4 to 6 months later. HCP self-efficacy for initiating conversations with overweight and underweight patients, measured immediately following the video, significantly improved from pre-video values ( Z = −5.6, P ≤ .001, and Z= −3.3, P = .001, respectively). Although improvements were not sustained 4 to 6 months later (overweight: P = .143, and underweight: P = .846), no significant decline was observed, suggesting retention of the skill. A majority of HCP respondents would recommend the video to a colleague and feel it will affect their practice. Thus, the present study suggests educational videos may be an effective tool for facilitating healthy weight-related conversations between HCPs and their pediatric patients.

Most environmental analytical methods for the determination of organochlorine pesticides (OCPs) are multi-residual with other organic compounds co-extracted and co-eluted. This has been observed in GC spectra using classical detectors like electron-capture detector (ECD) even after appropriate clean-up. This limitation could be resolved by using GC-MS methods which are more specific and selective. Thus, a commercial-grade endosulfan treated Theobroma cacao plantation was sampled. Representative samples comprising leaves, stem bark and pulp were obtained between 0.5 h and 60 days after treatment. Samples were analyzed for residual parent endosulfan ( α- and β-isomers) as well as the metabolite endosulfan sulphate using an ion trap GC-MS. The retention times and chromatogram peaks obtained for various endosulfan were identified and compared with reference standards, and confirmed with National Institute of Standards and Technology library. Results showed that the molecular ion at m/z 407 was exhibited by α- and β-endosulfan, representing the parent molecular ion M+• ([C9H6Cl6SO3]+•). The α-isomer was more thermally stable, hence exhibited more relative abundance. Other predominant peaks were 339, 307, 277, 265, 243, 241, 207, 195, 160, 159, 99 and 75 m/z. The peak at m/z 159 was the base molecular ion. For endosulfan sulphate, the peak at m/z 422 corresponded to parent molecular ion (M+•), while m/z 424 was due to isotopic pattern characteristic of the chlorine atom. The peaks at 387, 357, 289, 272, 229, 206, 170, and 120 m/z were characteristic for the sulphate metabolite. The m/z peak at 272 was the base molecular ion, while m/z 143 may be due to metabolite diol and lactone. These results showed that the various endosulfan species can be identified and confirmed simultaneously using a GC-MS.

The large cytoplasmic DNA viruses such as poxviruses, iridoviruses, and African swine fever virus (ASFV) assemble in discrete perinuclear foci called viral factories. Factories exclude host proteins, suggesting that they are novel subcellular structures induced by viruses. Novel perinuclear structures, called aggresomes are also formed by cells in response to misfolded protein (Johnston, J.A., C.L. Ward, and R.R. Kopito. 1998. J. Cell Biol. 143:1883–1898; García-Mata, R., Z. Bebök, E.J. Sorscher, and E.S. Sztul. 1999. J. Cell Biol. 146:1239–1254). In this study, we have investigated whether aggresomes and viral factories are related structures. Aggresomes were compared with viral factories produced by ASFV. Aggresomes and viral factories were located close to the microtubule organizing center and required an intact microtubular network for assembly. Both structures caused rearrangement of intermediate filaments and the collapse of vimentin into characteristic cages, and both recruited mitochondria and cellular chaperones. Given that ASFV factories resemble aggresomes, it is possible that a cellular response originally designed to reduce the toxicity of misfolded proteins is exploited by cytoplasmic DNA viruses to concentrate structural proteins at virus assembly sites.

Tematem artykułu są nazwy escape roomów (ER) w aspekcie ich intertekstualności. PierwszeER pojawiły się w Polsce przed pięcioma laty i od razu zdobyły wielką popularność,o której świadczy to, że w bieżącym roku zainteresowani tą nową formą rozrywki mogliskorzystać już z ponad tysiąca pokojów zagadek znajdujących się w wielu miastach zróżnicowanychpod względem wielkości i położonych w różnych częściach kraju. Ze względuna, uznawane za ewenement na skalę światową, wielkie zainteresowanie Polaków ER,mogą się one stać inspiracją do ciekawych, wielostronnych badań naukowych, w tym takżejęzykoznawczych. Jako nazwy własne miana ER należą do chrematonimii marketingowejzwiązanej z działalnością rozrywkową człowieka. Ich analiza pod kątem intertekstualnościjest z pewnością jednym z bardziej interesujących kierunków badawczych. Przy założeniu,że każda nazwa własna jest specyficznym tekstem, intertekst w sensie onimicznymoznacza nazwę (hipotekst) w innej nazwie (hipertekst). Proprialne interteksty mogą miećcharakter transtekstualizacji, transformacji, imitacji oraz intekstualizacji.W zgromadzonym materiale językowym (143 nazwy z trzech miast) dominują dwie grupynazw. Pierwszą tworzą onimy powstałe w wyniku transtekstualizacji, czyli przeniesienianazwy z jednego planu onimicznego do drugiego bez jakichkolwiek zmian formalnych,np. Peron 9 i ¾ − nazwa ER pochodząca z powieści o Harrym Potterze. W drugiej zaśznajdują się miana o charakterze intekstualizacji, tj. takie, w których strukturze nazwapierwotna pojawia się pośrednio (np. wymaga odczytania aluzji) lub poprzez w różnymstopniu zaawansowane wykorzystanie jej postaci (w tym cytaty), np. Bestie Peruna – nazwaER, którego scenariusz został osadzony w mitologii słowiańskiej, bo Perun to słowiańskiebóstwo gromowładne. Analizowane nazwy ER nie zaskakują swoją formą. Dla ich twórcówważniejsza od struktury nazwy jest jej semantyka, co jest zgodne z marketingową definicjąidealnej nazwy, a jednym z najważniejszych zadań omawianych onimów jest udział w coraztrudniejszej na polskim rynku walce o klienta, próba zainteresowania, zaintrygowania go oferowanym pokojem. Oprócz rywalizacji marketingowej intertekstualność nazw ERpośrednio wykorzystywana jest także do utrwalenia w społecznej pamięci nazw związanychz różnymi tekstami kultury.Intertekstualne nazwy ER to dynamicznie rozwijająca się kategoria współczesnychnazw własnych, które wymagają od ich kreatorów i odbiorców twórczej oraz odtwórczej,osadzonej w ogólnej wiedzy i kulturze, aktywności umysłowej gwarantującej właściweodczytanie nowych sensów ukrytych w tworzonych chrematonimach.

W opracowaniu skoncentrowano się na prezentacji opinii polskich emigrantów żyjących w Wielkiej Brytanii, którymi dzielili się oni między sobą w przestrzeni sieciowej – w ramach forum internetowego MojaWyspa.co.uk. Celem autorki było przeanalizowanie wpisów dotyczących dyskryminacji, opublikowanych po śmiertelnym napadzie na 40-letniego Polaka pod koniec sierpnia 2016 roku. Zdecydowano się na analizę wpisów koncentrujących się wokół tematu „Śmiertelne pobicie Polaka w Harlow”. Wyboru dokonano ze względu na liczbę wpisów (223 komentarze), a także z uwagi na zaangażowanie oraz emocjonalność poszczególnych wypowiedzi. Opinie użytkowników forum internetowego przeanalizowano ze względu na tematy, których się tyczyły – łącznie wydzielono 21 kategorii tematycznych. Pośród 223 wpisów aż 143 dotyczyły różnych form dyskryminacji, ataków ksenofobicznych, chęci obrony przed nimi, a także – wskutek tych zachowań – niechęci wobec Brytyjczyków. Zebrane dane wskazują, że Polacy w coraz większym stopniu czują się wyobcowani w Wielkiej Brytanii.

Przedmiot prezentowanych badań stanowiło szkolnictwo podstawowe zawężone do I i II etapu edukacyjnego (klasy I–III i IV–VI) na obszarach wiejskich województwa małopolskiego. Celem opracowania było wskazanie uwarunkowań funkcjonowania sieci szkół podstawowych oraz konsekwencji likwidacji szkół w kształceniu młodzieży. W artykule wykorzystano dane z lat 2000–2012 dotyczące liczby uczniów oraz szkół podstawowych, a także uczących w tych szkołach nauczycieli oraz stanu zaludnienia miejscowości Małopolski, udostępnione przez BDL GUS. Do realizacji postawionego celu badawczego wykorzystano również wyniki własnych badań bezpośrednich, przeprowadzonych w szkołach za pomocą metody sondażu diagnostycznego, oraz studia literatury przedmiotu, w tym aktów prawnych. Badaniom poddano 12 szkół podstawowych zlokalizowanych w powiecie miechowskim. Objęto nimi dwie grupy respondentów. Pierwszą stanowili opiekunowie uczniów, a drugą – dyrektorzy szkół. Badanie objęło 705 osób. W wyniku niekorzystnych tendencji demograficznych (ryc. 1) w województwie małopolskim w latach 2000–2012 na obszarach wiejskich liczba uczniów zmniejszyła się o 30% (ryc. 2). W konsekwencji likwidacji uległy 143 szkoły podstawowe, co stanowiło 12% ich ogólnej liczby (ryc. 3). Zamknięto głównie małe szkoły wiejskie, z obszarów typowo rolniczych w północno-wschodniej części województwa oraz z jego słabiej zaludnionych obszarów południowo-wschodnich (ryc. 4). W mniejszym stopniu proces ten objął miasta, gdzie spadek liczby dzieci w przeliczeniu na szkołę był znacznie wyższy w porównaniu do obszarów wiejskich. Liczba zlikwidowanych szkół byłaby zapewne znacznie większa, gdyby nie aktywność lokalnych społeczności. Korzystały one z możliwości przejęcia szkoły dzięki zakładaniu stowarzyszeń i organizacji społecznych oraz w dalszym etapie – zmianie organu prowadzącego (ryc. 5). W konsekwencji tych procesów znacznie zmieniło się w regionie rozmieszczenie szkół. Badania przeprowadzone w szkołach powiatu miechowskiego wskazują, że średni czas dojazduz miejsca zamieszkania do placówki wynosi 21 min, a najdłuższy jest do tych szkół, w otoczeniu których zlikwidowano minimum dwie placówki (ryc. 6). Najwięcej uczniów, bo ok. 60%, dojeżdża do badanych szkół autobusami. Bezpośrednio z formą organizacji dowozu wiąże się udział uczniów w zajęciach pozalekcyjnych. Tylko 44% uczniów z badanych szkół podstawowych powiatu miechowskiego uczęszczało na zajęcia pozalekcyjne.

Periodical growth monitoringand nutritional counseling can detect growth faltering earlier, de-termine the cause, and find alternatives to solve such problems.Objective To determine the benefit of nutritional counseling onknowledge, attitude, practice of mothers, and child growth.Methods A randomized controlled trial was conducted inSendangguwo, Semarang on 143 children of the treatment groupand 135 children of the control group. Nutritional counseling wasgiven to mothers in the treatment group by trained health volun-teers. Changes of weight for age Z-score (WAZ), height for age Z-score (HAZ), and weight for height Z-score (WHZ) were analyzedrepeatedly by using ANOVA. The differences of ΔWAZ, ΔHAZ, andΔWHZ between groups were compared by student t-test. GEE (gen-eralized estimating equation) analysis was used to analyze theeffect of confounding variables on the changes of WAZ.Results After 6 months of counseling, knowledge, attitude, andpractice of nutrition in the treatment group significantly increasedcompared to that of the control group (P<0.001). The WAZ, HAZ,and WHZ curves in the control group decreased. However, in thetreatment group, WHZ increased and there was stabilization ofWAZ. At the end of the study, treatment group had significantlyimproved their WAZ (P<0.001), HAZ (P=0.004), and WHZ(P<0.001) compared to that of the control group.Conclusion Nutritional counseling can improve knowledge, atti-tude, and practice of mothers, and has beneficial effects on childgrowth by WAZ, HAZ, and WHZ

Abstract Aims To determine the prevalence of hepatic steatosis in a cohort of previously healthy children and adolescents, with the use of abdominal computer tomography (CT). Methods Retrospective review of the Sickkids trauma database from (year 2004 to 2015). Inclusion criteria: previously healthy children ages 1-17yr having undergone an abdominal CT scan as a part of routine trauma assessment. Exclusion criteria: Involvement of spleen and/or liver in the injury, known metabolic condition, concurrent use of medications that could predispose to hepatic steatosis. Steatosis was defined as a liver spleen attenuation index (L/S AI) of <0.8. Anthropometrics and baseline demographics were collected. Statistical analyses were performed using Graphpad Prism 7. Results A total of 143 children were included in the analyses with a mean (SD) age of 7.12(4.26) years. 88 children were male (7.10(4.24) years old). The mean (SD) weight z score was 0.48 (0.97). Fifteen percent of the 137 children with a weight z-score between -2 to 2 had evidence of hepatic steatosis on imaging (using liver/spleen index <0.8). Twenty seven percent (6/22) of children with weight z-scores less than the 33rd percentile had L/S AI <0.8. An inverse correlation between weight z-scores and L/S AI was found in children >10 years (P<0.016) (Fig 1); however there was no correlation in pre-pubertal children (P<0.374). Conclusions Hepatic steatosis is highly prevalent in this cohort of healthy children in Ontario. Larger population based studies are needed to investigate the prevalence of hepatic steatosis in children across Canada. Funding Agencies None

AbstractObjective : To see the Left atrial appendage size (width and length) in ischemic cerebrovascular accident (CVA) patients.Design and method: Transesophageal echocardiography (TEE) was done in ischemic CVA patients after initial stabilization. We compared width length ratio(WLR) calculated from the average of width and length of LAA observed in earlier study by John P et al as controls. We chose this autopsy study as controls, as it is not possible to have TEE data in normal subjects.Results : Study group includes 143 patients (F:M::37:106) and control group was 400 subjects (F:M::200:200) from the previous study. The mean ± std of width and length of LAA in females and males in study group were 1.99±0.67, 2.397±0.58 and 2.19±0.73, 2.49±0.66 respectively. In females, WLR is more (0.83 ± 0.37) in study group than in control group (0.66±0.26) which is statistically significant (z=4.06, P < 0.000001). So also for males (study group: control group :: 0.88 ±0.39 : 0.71±0.28) which is also statistically significant (z=7.03, P < 0.000001). So, broad and short LAA could determine the formation and dislodgement of thrombus resulting in embolic stroke in both sexes.In conclusion, higher the width length ratio of left atrial appendage greater chances of embolic stoke.

Background: Advancement of skill, technology and perinatal medicine has led to improve survival of low birth weight babies during the last few decades but they have reported high incidence of growth failure during infancy and early childhood. The objective of the study was to find out the influence of perinatal risk factors on anthropometric outcome.Methods: A prospective cohort study conducted on 143 ELBW and VLBW babies admitted in Sick Newborn Care Unit (SNCU and PICU) of North Bengal Medical College and Hospital (NBMC), Darjeeling, West Bengal from 2016 to 2017 and discharged babies were followed up.Results: Total 143 neonates were studied at NBMC among male 82(57.3%) and female 61(42.7%), 95 were AGA and 48 were SGA babies. Significant positive correlations were found among birth weight, gestational age, perinatal infection (p<0.001). The mean weight for age (Mean±SD) was 7.615±1.1092 kg with median 7.8 kg. The mean length for age (Mean±SD) was 72.6±3.74 cm with median 73 cm. The mean head circumference for age (Mean±SD) was 42.5±2.12 cm median 43 cm. Adverse neonatal outcome associated with CRIB II score ≥10. Total CRIB II score with parameters of growth (<-2 Z score) like weight for age, length for age, weight for length and head circumference for age shows significant correlation (p<0.001).Conclusions: Perinatal risk factors are important determinant for future anthropometric outcome in very low and extremely low birth weight babies. They should be identified, and appropriate measures should be taken to achieve good outcome.

Full textAbstract:
ABSTRACT Context Brain-derived neurotrophic factor (BDNF) haploinsufficiency is associated with hyperphagia and obesity in both animals and humans. BDNF appears to function downstream of the leptin-melanocortin signaling pathway to control energy balance. The potential role of BDNF in the etiology of the severe hyperphagia associated with PWS has not been previously explored. Objective The aim was to compare BDNF concentrations in subjects with PWS and obese controls (OC) and lean controls (LC). Design and Setting We conducted a cross-sectional study at an outpatient clinical research center. Participants We studied 13 subjects with PWS [five males and eight females; mean ± sd: age, 11.0 ± 4.1 yr; body mass index (BMI)-Z, 2.05 ± 0.78], 13 OC (eight females, five males; age, 12.3 ± 2.7 yr; BMI-Z, 2.18 ± 0.61), and 13 LC (six females, seven males; age, 12.4 ± 2.6 yr; BMI-Z, −0.57 ± 0.73). Main Outcome Measure BDNF was measured in serum and plasma by ELISA. Analysis of covariance adjusted for age, sex, and BMI-Z. Results All groups were comparable for age (P = 0.50) and sex distribution (P = 0.49). BMI-Z was comparable between PWS and OC (P = 0.89) and lower in LC (P < 0.001). Adjusted serum BDNF was comparable (P = 0.35) in OC (mean ± sem: 13.5 ± 1.2 ng/ml) and LC (19.2 ± 1.3 ng/ml), but lower in PWS (8.3 ± 1.2 ng/ml; P = 0.01 vs. OC; P = 0.03 vs. LC). Adjusted plasma BDNF in PWS (217 ± 130 pg/ml) was lower than OC (422 ± 126 pg/ml; P = 0.02), but statistically comparable with LC (540 ± 143 pg/ml; P = 0.10). Conclusions Lower BDNF in PWS suggests insufficient central BDNF production because BDNF in peripheral circulation is believed to reflect cerebral BDNF output. Decreased BDNF may be a potential cause for the disordered satiety and morbid obesity associated with PWS. Further studies are needed to confirm this preliminary pilot study in a larger cohort of patients with PWS.

Abstract Introduction of bisphsophonates (BPs) treatment has changed the history of bone symptoms in multiple myeloma (MM) patients, as well as in metastasic cancers (MC). However, osteonecrosis of the jaw (ONJ) has been recently described in these patients. No clear mechanism is known, although length of BPs treatment, as well as dental procedures, have been argued as possible causes. We reviewed MM patients treated with BPs from two hospitals, in the last 7 years, with the aim of studying the incidence on ONJ and their correlation with: kind of BPs administered, time of treatment and dental procedures. MC patients treated with BPs were also reviewed in order to establish the influence of the disease in ONJ development. Non-parametric Mann-Whitney U-test was used in statistical analysis. From January 1999 to June 2006 a total of 225 MM patients were diagnosed in our two hospitals, 143 of them received BPs: 49 pamidronate (P) only, 64 zoledronic acid (Z) only, and 30 received P and Z (PZ) sequentially. P was administered at a doses of 90 mg every 4 weeks, and Z at a doses of 4 mgr every 4 weeks. 14 MM patients treated with BPs suffered ONJ: one patient (2%) treated with P, six (9,3%) with Z, and seven (23.3%) in the group receiving PZ. In the same period of time 353 MC patients were treated with BPs, two of them (0.6%) developed ONJ. Length of treatment, expressed in months, is shown in the table (in MC patients, only Z group was analyzed). Months of treatment Diagnosis P Z PZ Total Expressed as median and range. MM without ONJ 22.5 (4–52) 9.5 (1–28) 38 (12–72) 14 (1–52) MM with ONJ 28 12 (7–28) 43.5 (24–59) 28 (7–59) MC 8 (1–41) The longest administration of treatment was in PZ patients compared with P and Z(p<0.02), followed by P group that was longer than Z group (p<0.01). No difference was found between MC and MM groups in Z treatment length, neither between patients with and without ONJ inside each Z and ZP groups. Five ONJ patients suffered from dental procedures along BPs administration. In our series the incidence of ONJ is higher than that described in literature (4–10%), and it is very surprising the elevated incidence reached in patients treated with both BPs (23%). In our opinion, coincidental with other authors, the lasting of treatment might be one, but not the only, important factor, because in patients receiving P treatment duration was longer than Z but, ONJ incidence was lesser. For this reason we think that more potent BPs might have a role in ONJ development. Since MC patients receiving the same schedule of treatment with Z than MM do not develop ONJ so frequently, so it seems that the disease itself might play a role in ONJ incidence.

Introduction: Prior research generally confirms the importance of endurance exercises in preschool period and suggests shorter and less intensive exercises. However, little research has been conducted to show and evaluate different types for developing endurance in preschool period. Our research aims to find out which type of exercise is more suitable for developing endurance for a preschool age child compared to an adult, taking into account developmental characteristics.
Material and methods: A total of 69 preschool children (40 children aged 3 years and 29 children aged 5 years) were included in the study. We measured their heart rates during two types of endurance exercises (uninterrupted walking vs “method of game”). We compared the average heart rate and the actual frequency curves.
Results: Endurance exercise according to the “method of game” allows the child to adjust the effort more individually compared to uninterrupted walking when both exercises are performed with a group of pre-school children. A comparison of heart rate curves showed that when children partook in the “ method of game”, they achieved different heart rate values at the same time. A further analysis of heart rate with 5 selected “time stamps” between the two exercises showed that children achieved statistically significant higher heart rates when performing the “method of game” (1’: Z = 2.20; p = 0.028, r = 0.19; 3 ‘: Z = 4.64; p = 0.00, r = 0.39; 5’: Z = 3.23; p = 0.001, r = 0.27; 8’: Z = 3.82 p = 0.00, r = 0.32; 13 ‘: Z = 3.33; p = 0.001, r = 0.28). The comparison of the mean heart rate values over the entire 13-minute time interval between the execution of the “method of game” (M = 143, SD = 14) and uninterrupted walking (M = 132, SD = 9) was statistically significantly higher in favour of the “method of game” (Wilcox test: Z = 5.83, p = 0.00, r = 0.24). The Mann-Whitney-Test showed that 3-year-old children achieved statistically significantly higher average heart rate during the “method of game” (Z = -2.34 p = 0.020, η² = 0.08) as well as during uninterrupted walking (Z = 3.17 p = 0.002, η² = 0.15). No statistically significant differences between boys and girls were confirmed.
Conclusions: Based on the results obtained, we believe that endurance exercise according to the “method of game” is more suitable for a developing preschool child than uninterrupted walking. The “method of game” also allows the simultaneous implementation of endurance exercise in heterogeneous groups, since the children adapt to the effort themselves, regardless of age. We believe that other types of endurance exercises should be researched and all age groups of preschool children should be included in the research.

Zusammenfassung Ziel Für SPGS wurde inhaltsanalytisch und unter Berücksichtigung personen- bzw. tätigkeitsbezogener Belastungs- und Beanspruchungsmerkmale erfasst, welche Maßnahmen aus Sicht von LK zur Verbesserung der gesundheitlichen Situation am Arbeitsplatz beitragen können. Methodik Die Daten stammen aus einer vom Institut für Lehrergesundheit (IFL) von August 2013 bis April 2015 an 14 SPGS in Rheinland-Pfalz durchgeführten schriftlichen Querschnittserhebung. Die Teilnahmequote liegt bei 46,3% (143/309 LK). Antworten auf die offene Frage „Welche konkreten berufsbezogenen Maßnahmen würden zu einer Verbesserung Ihres Wohlbefindens oder Ihrer gesundheitlichen Situation am Arbeitsplatz beitragen?“ wurden kategorisiert und quantifiziert. Es erfolgte eine Item-Non-Responder-Analyse. Logistische Regressionsanalysen dienten dazu, Belastungs- oder Beanspruchungsmerkmale zu identifizieren, die mit der Benennung spezifischer Kategorien in Zusammenhang stehen. Ergebnisse Es wurden die Angaben von 143 LK ausgewertet. 79 LK machten insgesamt 362 Vorschläge zur Verbesserung der gesundheitlichen Situation am Arbeitsplatz. Die Abgabe eines Vorschlags wurde nicht von soziodemografischen Variablen beeinflusst. 33,6% der LK thematisierten die baulichen/physikalischen Arbeitsbedingungen, bspw. klimatische oder akustische, oder die Schaffung bislang fehlender Rückzugsräume. 29,4% der LK machten Vorschläge zu personalstrukturellen Maßnahmen (Stichwort: „Doppelbesetzung“). 9,1% der LK führten Aspekte der kollegialen Zusammenarbeit an. Den Regressionsanalysen zufolge steht die Benennung einzelner Kategorien in Zusammenhang mit spezifischen tätigkeitsbezogenen Belastungsmerkmalen. Zudem weisen LK, die sich stärker beansprucht fühlen, hier: ihre Arbeit als (sehr) stark gesundheitsgefährdend wahrnehmen, eine signifikant höhere Chance (Odd) auf, Vorschläge der Kategorie „KollegInnen“ (aOR 3,71; 95%KI 1,00–13,76) oder „Externe Unterstützung“ (z. B. Supervision) (aOR 3,92; 95%KI 1,15–13,41) zu machen als weniger stark beanspruchte LK. Schlussfolgerungen An SPGS tätige LK zeigen sich bereit, sich aktiv an der gesundheitsbezogenen Organisationsentwicklung zu beteiligen. Die kombinierte Auswertung qualitativer und quantitativer Daten erleichtert die Entwicklung problem- und zielgruppenspezifischer Interventionsansätze.

Introduction/Objective. Preterm birth (PB) is the most important reason of neonatal mortality, and the second most common direct cause of death for children under the age of five years. The aim of this study was to analyze the clinical features and outcomes of preterm infants. Methods. The clinical data of 307 preterm infants delivered in the Qingdao University hospital from January 1, 2012 to December 31, 2012 were retrospectively analyzed. Results. The incidence of PB was 6.52%. There were 143 cases of preterm prelabour rupture of membranes (PPROM) (46.58%), 66 cases of spontaneous PB (21.5%), and 98 cases of therapeutic PB (31.92%). Deliveries with gestational weeks (GW) < 32 were mainly vaginal (60.72%), but deliveries with GW ? 32 exhibited higher C-section rate (60.99%) than the vaginal delivery rate (p < 0.05). The birth weight was 2,340.46 ? 606.26 g, and the Z-score at birth was -0.15 ? 1.08. The Z-score in the group with GW within 28 to 31+6 weeks was less than that in the group with GW within 32 to 33+6 and with GW ? 34 (? < 0.05). The average hospital stay of preterm infants was 15.17 ? 12.35 days, and the most common complication in these preterm infants was respiratory distress syndrome with 13.92%. Conclusion. PB could cause a variety of serious complications in infants. The main causes of PB, such ?? PPROM, should be actively prevented and treated; meanwhile, preterm infants should also be actively treated so as to improve their outcomes.

AbstractThe new oxalate mineral antipinite is found in a guano deposit located on the Pabellón de Pica Mountain, Iquique Province, Tarapacá Region, Chile. Associated minerals are halite, salammoniac, chanabayaite, joanneumite and clays. Antipinite occurs as blue, imperfect, short prismatic crystals up to 0.1 mm × 0.1 mm × 0.15 mm in size, as well as their clusters and random aggregates. The mineral is brittle. Mohs hardness is 2; Dmeas = 2.53(3), Dcalc = 2.549 g cm–3. The infrared spectrum shows the presence of oxalate anions and the absence of absorptions associated with H2O molecules, C–H bonds, CO32–, NO3– and OH– ions. Antipinite is optically biaxial (+), α = 1.432(3), β = 1.530(1), γ = 1.698(5), 2Vmeas = 75(10)°, 2Vcalc = 82°. The chemical composition (electron-microprobe data, C measured by gas chromatography of products of ignition at 1200°C, wt.%) is Na2O 15.95, K2O 5.65, CuO 27.34, C2O3 48.64, total 99.58. The empirical formula is K0.96Na3.04Cu2.03(C2.00O4)4 and the idealized formula is KNa3Cu2(C2O4)4. The crystal structure was solved and refined to R = 0.033 based upon 4085 unique reflections with I > 2σ(I). Antipinite is triclinic, space group P1, a = 7.1574(5), b = 10.7099(8), c = 11.1320(8) Å, α = 113.093(1), β = 101.294(1), γ = 90.335 (1)°, V = 766.51(3) Å3, Z = 2. The strongest reflections of the powder X-ray diffraction pattern [d, Å (I,%) (hkl)] are 5.22 (40) (111), 3.47 (100) (032), 3.39 (80) (210), 3.01 (30) (033, 220), 2.543 (40) (122, 034, 104), 2.481 (30) (213), 2.315 (30) (143, 310), 1.629 (30) (146, 414, 243, 160).

Full textAbstract:
Infants breastfeeding from mothers consuming aflatoxin contaminated foods may be exposed to aflatoxin M1(AFM1), a metabolite of aflatoxin B1. This study estimated the association between AFM1exposure levels and growth indicators, for infants under six months of age in the Rombo district in Northern Tanzania. A total of 143 infants and their mothers were involved. Breast-milk samples, infants' anthropometric data and 24 h dietary recall for mothers were taken at the 1st, 3rdand 5thmonths of children age. AFM1contaminations in the samples were determined using HPLC. Aflatoxin M1exposure by an infant was estimated by multiplying contamination in the breast milk consumed by him/her with the breast milk intake recorded by the United States Environmental Protection Agency for infants of his/her age divided by the infant's body weight. All the breast-milk samples were contaminated by AFM1at levels ranging from 0.01 to 0.55 ng/ml. Above 90% of samples exceeded the EU limit of 0.025 ng/ml for infants' foods while over 76% exceeded the EU limit of 0.05 ng/ml for dairy milk and milk products. Only 1% of the samples exceeded the limit of 0.5 ng/ml set for dairy milk in the United States and several countries in Asia. AFM1Exposures ranged from 1.13-66.79 ng/kg body weight per day. A small but significant (P<0.05) inverse association was observed between AFM1exposure levels and weight for age Z-score or height for age Z-score. Appropriate strategies should be applied to minimise aflatoxin B1exposure in lactating mothers in order to protect infants from AFM1exposure.

Room-temperature single-crystal X-ray studies are recorded for a number of ‘acid salts’ formed between Group 1 salts of 4-nitrophenol, M(4-np), and the parent ligand 4-npH, variously hydrated. The 1 : 1 salts M(4-np)(4-npH).x H2O are found for all of M = Li, Na, K, Rb and Cs. The lithium adduct (tetrahydrate) is monoclinic, C2/c, a 19·438(4), b 11·207(2), c 7·421(2) Å, β 91·38(2)°, Z = 4, conventional R on |F| being 0·043 for 1369 independent ‘observed’ (I > 3σ(I)) diffractometer reflections. The sodium adduct (dihydrate) is monoclinic, C2, a 2·174(3), b 3·674(2), c 10·358(1) Å, β 117·21(1)°, Z = 2, R 0·035 for No 1092; the potassium adduct (monohydrate) is monoclinic, C 2/c, a 22·10(1), b 3·798(3), c 21·270(6) Å, β 120·97(4)°, Z = 4, R 0·050 for No 1065. The isomorphous rubidium and caesium monohydrates are triclinic, P-1, a ≈ 11·9, b ≈ 10·2,c ≈ 6·3 Å, α ≈ 90, β ≈ 92, γ ≈ 112°, Z = 2, R 0·042, 0·028 for No 2340, 3053 respectively. For M = Rb, a 1 : 3 adduct Rb(4-np).3(4-npH) is also obtained (with an isomorphous thallium counterpart recorded elsewhere): a 12·143(5), b 11·50(1), c 11·36(1) Å, α 114·38(9), β 110·54(6), γ 96·73(6)°, Z = 2, R 0·034 for No 3945. The lithium salt may be represented as [Li(OH2)4]+ (4-npH.4-np)½-. The cation lies disposed about a crystallographic 2 axis; the anion, close to an axis, confronts its rotational image, with the associated hydrogen atom modelled as disordered between them, rather than located on the 2 axis. The sodium salt is a sheet structure, the six-coordinate sodium atoms being disposed on a crystallographic 2 axis and linked up that axis ... Na(µ-O)2Na(µ-O)2Na ... by bridging water molecule oxygen atoms, while symmetry-related trans O-nitrophenoxide moieties are bridged by confronting phenoxide oxygen atoms about an associated hydrogen atom provisionally disposed on a 2 axis also. The potassium salt structure is developed from this array, modelled with disordered potassium atoms, now lying off the 2 axis, 0·922(2) Å apart. In the rubidium/caesium structure, columns of oxygen-bridged metal ions are disposed about c, crosslinked by O-nitro-bonded phenoxide moieties, with confronting phenoxide oxygen atoms about a shared associated hydrogen.

Full textAbstract:
AbstractThe core structure of early-type galaxies is revisited in light of recent results from the ACS Virgo and Fornax Cluster Surveys. These surveys are comprised of HST/ACS g, z band images for a representative sample of 143 early-type galaxies, spanning a factor 720 in B-band luminosity. The data indicates a clear transition in the core structure going from the brightest to the faintest galaxies. In contrast to previous claims, however, this transition is found to be a continuous function of galaxy magnitude. We characterize the core structure in terms of deviations of the observed surface brightness profile – measured within ~ 2% of the galaxy effective radius – relative to the inner extrapolation of the Sérsic law that best fits the profiles on larger scales. Virtually all galaxies fainter than MB ~ −20 mag contain distinct stellar nuclei, and are described by surface brightness profiles that lie above the Sérsic extrapolation, while the reverse is true for brighter galaxies. The latter are also known to host supermassive black holes. A relation between SBHs and stellar nuclei is suggested by the fact that both types of “central massive objects” contain the same fraction, 0.2% of the total mass of the host galaxy.

Those imidazoles bearing an N-alkyl substituent and having a hydrogenat C2 react to give the 2-bromo products, while the N-H imidazoles react togive N-cyano derivatives. The product(s) from thereaction of 1,2-dimethylimidazole with BrCN could not be characterized. Of thecomplexes, only[Co(NH3)5(im)](ClO4)2 reacts, giving the 2-bromoproduct.

(2010, Advances in Mathematical Modeling and Experimental Methods for Materials and Structures. Solid Mechanics and Its Applications. Springer: Berlin, 249–254.; 2015, Celebrating the Centenary of Timoshenko’s study of effects of shear deformation and rotary inertia. Appl. Mech. Rev.67, 1–11.; 2017, Critical contrasting of three versions of vibrating Bresse-Timoshenko beam with a crack. Int. J. Solids Struct. 109, 143–151.). These equations are free of the so-called ‘second spectrum’ phenomenon, and they have important consequences on stabilization setting. Specifically, following Almeida Júnior and Ramos (2017, On the nature of dissipative Timoshenko systems at light of the second spectrum. Z. Angew. Math. Phys.68, 31.) in a recent contribution that shows that damping effects eliminate the consequences of this spectrum for equal wave propagation velocities, we prove that time delay effects are able of stabilizing the truncated version regardless of any relationship between coefficients of system. It is concluded that dissipative truncated versions of Bresse–Timoshenko equations are advantageous over the classical Bresse–Timoshenko equations in stabilization context.

ABSTRACTThe crystal structure of the mineral gortdrumite, a rare copper-mercury-iron sulfide, was solved using intensity data collected using a crystal from the Neuschurf adit, Leogang, Salzburg, Austria. This study revealed that the structure is triclinic, space groupP$\bar 1$, with cell parameters:a= 9.677(4),b= 9.865(5),c= 11.992(5) Å, α = 77.85(4), β = 79.42(3), γ = 76.30(4)°,V= 1076.5(8) Å3andZ= 1. The refinement led to anRindex of 0.0833 for 3335 independent reflections and 143 parameters. Twelve S sites (one with half occupancy) and eighteen metal sites (5 Hg, 12 Cu and 1 Fe) occur in the crystal structure of gortdrumite. Mercury cations link two sulfur atoms in a linear coordination, Cu cations are found in various low-coordination (2, 3 and 4) sites, in agreement with the Cu preference for such environments, and Fe in tetrahedral coordination. Metal–metal interactions are also present and these contacts are discussed in relation with other copper sulfides, intermetallics and pure metals. Electron microprobe analyses of the crystal used for the structural study led to the formula Cu24.83Fe1.73Hg9.09S22.35, on the basis of 58 atoms. On the basis of information gained from the structural and chemical characterization, the crystal-chemical formula was revised to Cu24Fe2Hg9S23(Z= 1) instead of (Cu,Fe)6Hg2S5as reported previously.
